The sound is listed with Nicole TV, which points to its origin as a short vocal moment shared online rather than a song or film quote. Its appeal comes from the nonsense rhythm itself: woop and doop are easy to remember, easy to imitate, and fit the quick pace of short videos. As a soundboard clip, it has been picked up by creators who want a light, repeatable reaction sound that does not need context to land. That simplicity is why it keeps appearing in edits, streams, and meme compilations.
